PCE-DRU 1 is a handheld digital refractometer used to determine the urea (NH2) 2C0 (AdBlue) content / refractive index of liquid in the 0 … 51 % / 1.3330 … 1.4056 nD measuring range. This waterproof IP65-rated digital refractometer features automatic temperature compensation (ATC) from +10 … +40 °C / +50 … +104 °F, as well as a large, easy-to-read LCD that shows both the measured value and the temperature.

Measurement parameters:
  Urea (NH2) 2C0, refractive index, temperature

• Measurement range: 0 … 51 % 
• Resolution: 0.1 % 
• Accuracy: ±0.2 % 
• Automatic temperature compensation (ATC)
